Abstract
A pressure transmitter includes a sensor assembly having a hollow body housing a pressure sensor. The pressure transmitter also includes a support body which is made of a first material, and an interface body which is connected to the support body and which is made of a second material different from the first material. A first isolation diaphragm is fixed onto the interface body and is made of the same material of the interface body. The first isolation diaphragm is in fluid communication with the pressure sensor and is configured for interfacing with a process fluid.
